butterflies

I was watching Secretary today (I always go back to that movie), and I always notice something new each time. This time I noticed the abundance of butterflies. Lee has a butterfly sticker on her backpack, and I spotted at least 10 butterfly-themed stuff (butterfly shaped notebook, butterflies on her self-harm kit, butterfly lamp, butterfly doorway decor type stuff, and lots more). Do you think there's any meaning behind this or the director is just having fun with it? I know from watching the commentary that there's a theme of purple but nothing about butterflies.
